It work really well. I connect directly from the app no need to scan QR. Every time I travel, I’m only gonna buy eSIM on trip.com from now on. On some occasion it can be a little slow. But it’s nothing to make a fuss about.

The network card provided by this adapter in Osaka demonstrated a very stable and fast signal, and was easy to install. It is also very reasonably priced.
